AS Design Studio is executes BW Queries in serial mode. I hope in feature release parallel execution process would be included. To show the data from the same data source in multiple charts/components without editing the initial view of the DS- You can follow the below process.
In this example I need to show 0FIAR_CO3 data in Cross_Tab and Chart.
Just in the Applicationa–> Properties–> Events–> On Startup
Browse and mention below script. Modify the script according to your requriment.
if (CROSSTAB_1.isVisible() == true)
if (CHART_3.isVisible() == true)
